She describes Howl as "her best student", but in the books Penstemmon tutored Howl in magic. Perhaps she taught Howl before he came to Ingary, and he learned how to travel between worlds from her, then studied Ingary's magic with Penstemmon. * If Suliman was a schoolteacher, this might be why that was also the profession Angorian pretended. * Alternatively, movie Suliman is also Penstemmon.
